0 Introduction
This European Standard contains requirements and
acceptance criteria (including test methods) for
safety-related parameters for haemodialysers,
haemodiafilters, haemofilters, haemoconcentrators and
the extracorporeal circuits for these devices
This European Standard contains only those
requirements that are specific to the devices
concerned Non-specific requirements are covered by
references to other European or International
Standards, listed in the normative references section
Since non-toxicity is anticipated to be the subject of a
future standard, this standard does not cover
non-toxicity
1 Scope
This European Standard specifies requirements for
sterile, single use haemodialysers, haemodiafilters,
haemofilters, haemoconcentrators and the
extracorporeal circuits for these devices (including any
integral accessory lines, such as fluid and infusion lines
and lines for connection to pressure monitors)
intended for renal care and cardiovascular use on
humans
This European Standard does not apply to
extracorporeal circuits for cardiovascular use or to
other extracorporeal blood exchange devices, such as
plasmafilters, haemoperfusion devices, vascular access
devices, oxygenators, active medical devices or devices
for peritoneal dialysis
2 Normative references
This European Standard incorporates by dated or
undated reference, provisions from other publications
These normative references are cited at the
appropriate places in the text and the publications are
listed hereafter For dated references, subsequent
amendments to or revisions of any of these
publications apply to this European Standard only
when incorporated in it by amendment or revision For
undated references the latest edition of the publication
referred to applies

3 Definitions
For the purposes of this European Standard, the following definitions apply:
3.1 blood compartment
Part of haemodialysers, haemodiafilters, haemofilters and haemoconcentrators through which blood is intended to pass
3.2 clearance
Volume of a solution from which a solute is completely removed per unit time
3.3 dialysing fluid; dialysate; dialysis fluid
Solution which is intended to exchange solutes and/or water with blood during haemodialysis or
haemodiafiltration
3.4 dialysing fluid compartment
Part of a haemodialyser or haemodiafilter through which dialysing fluid is intended to pass
3.5 haemoconcentration
Process whereby excess fluid, and possibly electrolytes, are removed from diluted blood across a semipermeable membrane
Trang 83.6 haemoconcentrator
Device intended to perform haemoconcentration
3.7 haemodiafilter
Device intended to perform haemodiafiltration
3.8 haemodiafiltration
Process whereby solute imbalances in a patient's blood
are corrected by means of simultaneous filtration and
diffusion across a semipermeable membrane and
replacement with an appropriate physiological fluid
NOTE This process normally includes fluid removal.
3.9 haemodialyser
Device intended to perform haemodialysis
3.10 haemodialysis
Process whereby solute imbalances in a patient's blood
are corrected, mainly by diffusion across a
semipermeable membrane
NOTE This process normally includes fluid removal.
3.11 haemofilter
Device intended to perform haemofiltration
3.12 haemofiltration
Process whereby solute imbalances in a patient's blood
are corrected, mainly by filtration across a
semipermeable membrane and replacement with an
appropriate physiological fluid
NOTE This process normally includes fluid removal.
3.13 transmembrane pressure
Hydrostatic pressure exerted across a semipermeable
membrane
NOTE For practical reasons the mean transmembrane pressure is
generally expressed as either:
a) the difference between the arithmetic means of inlet and
outlet pressures of the blood and dialysing fluid compartments
of a haemodialyser or a haemodiafilter; or
b) the difference between the arithmetic mean of the inlet and
outlet pressures of the blood compartment and the filtrate
pressure of a haemofilter or a haemoconcentrator.
3.14 access port
Component intended to provide access to the interior
of the extracorporeal circuit

simultaneous concentration of the same solute in the
plasma
